Abstract
Description
本発明は、釣り糸としての十分な強度を持ち、適度な伸びと伸縮回復性をバランス良く兼ね備えた高性能な釣り糸およびその製造方法に関するものである。 The present invention relates to a high-performance fishing line having a sufficient strength as a fishing line and having a suitable balance between elongation and expansion / contraction recovery, and a method for producing the same.
近年、釣具の進化はめざましく、中でも釣り糸の分野では、それぞれの釣り用途に最も適した特性を持つ釣り糸の開発が盛んに行われており、特にポリアミド繊維、ポリフッ化ビニリデン繊維、ポリエステル繊維、高密度ポリエチレン繊維、ポリアリレート繊維、アラミド繊維、金属細線などを使用した釣り糸が、対象魚やその釣り方に合わせて色々と提案されている。 In recent years, the evolution of fishing gears has been remarkable, and in the fishing line field, fishing lines having the most suitable characteristics for each fishing application have been actively developed, especially polyamide fibers, polyvinylidene fluoride fibers, polyester fibers, high density Various fishing lines using polyethylene fibers, polyarylate fibers, aramid fibers, fine metal wires, and the like have been proposed according to the target fish and how to fish.
中でも高密度ポリエチレン繊維、ポリアリレート繊維、アラミド繊維、ガラス繊維、金属細線などの高強度新素材繊維からなる釣り糸や、これらの繊維を混合して製紐または撚り合わせてなる釣り糸（以下、新素材釣り糸と言う）は、高強度であることから、ほかの素材からなる釣り糸に比べ細い釣り糸に形成できること、細い釣り糸に形成し得るため潮の流れによる流水抵抗や仕掛けを投入する時の空気抵抗を受けにくく、魚の居る水深（いわゆる棚）に仕掛けをいち早く合わせることが可能であること、破断伸度が低いため魚が掛かった時の当たりが伝わりやすいことなどの様々な利点を持つことから、特に船釣り用、投げ釣り用の道糸として使用されている。 Among them, fishing lines made of high-strength new material fibers such as high-density polyethylene fiber, polyarylate fiber, aramid fiber, glass fiber, and fine metal wire, and fishing line made by mixing or twisting these fibers (hereinafter referred to as new material) The fishing line) has high strength, so it can be formed into a thin fishing line compared to fishing lines made of other materials, and it can be formed into a thin fishing line. Especially because it is difficult to receive, and it is possible to quickly adjust the mechanism to the depth of water where the fish is located (so-called shelf), and because it has a low breaking elongation, it is easy to convey the hit when the fish is caught, especially It is used as a road thread for boat fishing and throwing fishing.
また、複数の繊維から形成して成る新素材釣り糸としては、芯糸に合成樹脂マルチフィラメント糸条を配し、その周りに鞘糸として合成繊維マルチフィラメントの撚り糸を巻き付けたカバーリング糸であって、芯糸と鞘糸のなす角度と撚り糸の撚り角度との差を２５°以下にすることにより、優れた破断強度と結節強度を持ち、且つ低伸度で耐摩耗性に優れた釣り糸（例えば、特許文献１参照）、ガラス繊維からなる芯糸と、複数本のガラス繊維以外の繊維からなる鞘糸で製紐され、且つ芯糸と鞘糸および鞘糸同士がバインダー樹脂により一体化された伸度５％以下の糸条（例えば、特許文献２参照）が既に知られている。 In addition, as a new material fishing line formed from a plurality of fibers, it is a covering yarn in which a synthetic resin multifilament yarn is arranged on a core yarn, and a synthetic fiber multifilament twisted yarn is wound around it as a sheath yarn. By setting the difference between the angle between the core yarn and the sheath yarn and the twist angle of the twisted yarn to 25 ° or less, a fishing line having excellent breaking strength and knot strength, low elongation, and excellent wear resistance (for example, , Patent document 1), a core yarn made of glass fiber and a sheath yarn made of fibers other than a plurality of glass fibers, and the core yarn, the sheath yarn and the sheath yarn are integrated with a binder resin. A yarn having an elongation of 5% or less (for example, see Patent Document 2) is already known.
しかし、これら従来の新素材釣り糸は、十分な強度を持つものの、伸度が低いために、魚が掛かった際に魚が逃げようとして暴れると、釣り糸がその振動を十分に吸収できず、魚が針から外れて逃げてしまうというトラブルを頻繁に生じていた。 However, these conventional new material fishing lines have sufficient strength, but because the elongation is low, when the fish catches the fish when it catches it, the fishing line cannot absorb the vibrations enough, Frequently ran out of the needle and escaped.
特にこのトラブルは、ルアーフィッシングや磯釣りなど船釣りや投げ釣りに比べて釣り人と魚の距離が短い釣りで頻繁に起きており、この点で従来の新素材釣り糸は、船釣り、投げ釣り以外の用途には未だ実用性に欠けたものであった。 In particular, this problem occurs more frequently in fishing where the distance between the angler and the fish is shorter than in boat fishing and throwing fishing such as lure fishing and carp fishing. In this respect, the conventional new material fishing line is other than ship fishing and throwing fishing However, it was still lacking in practical use.
また、多くの釣り人が軽い仕掛けを遠くに飛ばすために有効なスピニングリールを使用するが、従来の新素材釣り糸を道糸に使用した場合は、釣り糸の伸びが小さいために、魚が掛かっていない状態で道糸をスプールに巻き取ると道糸が緩くスプールに巻かれてしまい、再び仕掛けを投入するとスプール上で道糸が引っ掛かり、スプールから順次道糸が出ていかずに一度にスプールから出てしまうバックラッシュと呼ばれる現象を頻繁に起こすことになるため、従来のモノフィラメント製の道糸に比べて扱いにくいものであった。 Also, many anglers use spinning reels that are effective for flying light devices far away, but when using a traditional new material fishing line as a road line, the fishing line is small and fish is hanging. If the thread is wound around the spool in a state where there is not, the thread is loosely wound on the spool.When the mechanism is turned on again, the thread is caught on the spool, and the thread is not ejected from the spool at once without being sequentially ejected from the spool. This often causes a phenomenon called backlash, which is more difficult to handle than conventional monofilament road yarns.
このように、従来の新素材釣り糸は、船釣り用途や投げ釣り用途に対しては十分に実用性のあるものではあったが、その他の釣り用途に対してはその実用性が低いため、あらゆる釣り用途に利用できる新素材釣り糸の実現が強く望まれていた。
本発明は、上述した従来技術における問題点の解決を課題として検討した結果達成された物である。 The present invention has been achieved as a result of examining the solution of the problems in the above-described prior art as an object.

釣り糸としての十分な強度を持ち、従来の新素材釣り糸に比べて適度な伸びと伸縮回復性をバランス良く兼ね備え、且つ従来のモノフィラメント製釣り糸と同等の扱い易さを有する本発明の釣り糸は、熱可塑性樹脂モノフィラメントからなる芯糸の周囲に一本以上の鞘糸を製紐または撚り合わせてなる釣り糸であって、この釣り糸の直径が０．０５〜０．６ｍｍの範囲にあり、且つ釣り糸の破断強度が１５００Ｎ／ｍｍ２以上、破断伸度が１０〜４０％の範囲にあるとともに、長さＨ０の釣り糸に引張速度３００ｍｍ／分で荷重を掛けてゆき、破断強度の５％の荷重が掛かった時点の釣り糸の長さをＨ、さらに破断強度の５％の荷重を１分間掛けた状態で放置した後、３００ｍｍ／分の速度で荷重を取り除いた後の釣り糸の長さをＨ１とした際に次式１００×（Ｈ−Ｈ１）／（Ｈ−Ｈ０）で求められる瞬間回復率が７０〜１００％の範囲にあることを特徴とする。 The fishing line of the present invention, which has sufficient strength as a fishing line, combines moderate elongation and stretch recovery with a good balance as compared with a conventional new material fishing line, and has the same ease of handling as a conventional monofilament fishing line, A fishing line formed by stringing or twisting one or more sheath threads around a core line made of a plastic resin monofilament, the diameter of the fishing line being in the range of 0.05 to 0.6 mm, and the breaking of the fishing line The strength is 1500 N / mm 2 or more, the elongation at break is in the range of 10 to 40%, and a load is applied to the fishing line of length H 0 at a tensile speed of 300 mm / min, and a load of 5% of the breaking strength is applied. after the length of the fishing line at the time it was left H, further 5% of the load of the breaking strength in a state of over one minute, the length of the fishing line after removal of the load at 300 mm / min and H 1 Following formula 100 × (H-H 1) / (H-H 0) at the instant determined recovery rate is characterized in that in the range of 70% to 100% when.
まず、芯糸となる熱可塑性樹脂モノフィラメントの構成素材としては、例えば６ナイロン、６６ナイロン、６１０ナイロン、６１２ナイロン、６／１２共重合ナイロン、６／６６共重合ナイロンなどのポリアミド樹脂またはこれらの共重合体、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート、ポリシクロヘキサンジメチレンテレフタレートなどのポリエステル樹脂またはこれらの共重合体、ポリフッ化ビニリデン、エチレン・テトラフルオロエチレン共重合体テトラフルオロエチレン・ヘキサフルオロプロピレン・フッ化ビニリデン共重合体、テトラフルオロエチレン・ヘキサフルオロプロピレン・フッ化ビニリデン共重合体などのフッ素樹脂、ポリフェニレンサルファイド、ポリエチレン、ポリプロピレンなどのポリオレフィン樹脂、スチレン系、ポリオレフィン系、ポリ塩化ビニル系、ポリウレタン系、ポリエステル系、ポリアミド系、１，２ポリブタジエン系、トランスイソプレン系、フッ素ゴム系、塩素化ポリエチレン系エラストマー、コハク酸、アジピン酸、および１，４ブタシジオールなどからなるランダムコポリマーまたはこれらランダムコポリマーとポリブチレンサクシネートまたは／およびポリエチレンサクシネートのブレンドポリマーである脂肪族ポリエステルが挙げられ、さらにこれらを２種類以上ブレンドしたものも使用することができる。 First, as a constituent material of the thermoplastic resin monofilament used as the core yarn, for example, polyamide resin such as 6 nylon, 66 nylon, 610 nylon, 612 nylon, 6/12 copolymer nylon, 6/66 copolymer nylon, or the like can be used. Polymers, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycyclohexanedimethylene terephthalate or copolymers thereof, polyvinylidene fluoride, ethylene / tetrafluoroethylene copolymer tetrafluoroethylene / hexafluoropropylene / Fluorine resins such as vinylidene fluoride copolymer, tetrafluoroethylene / hexafluoropropylene / vinylidene fluoride copolymer, polyphenylene sulfide, polyethylene, polypropylene Polyolefin resins such as pyrene, styrene, polyolefin, polyvinyl chloride, polyurethane, polyester, polyamide, 1,2 polybutadiene, transisoprene, fluororubber, chlorinated polyethylene elastomer, succinic acid, adipine Examples include aliphatic polyesters that are random copolymers of acid and 1,4 butadiol or the like, or blend copolymers of these random copolymers with polybutylene succinate or / and polyethylene succinate, and blends of two or more of these are also used can do.
特に、本発明の釣り糸においては、優れた伸縮性（瞬間回復）を有するとともに、加工性に優れていることから、ポリアミド系樹脂や脂肪族ポリエステルの使用がより好ましい。 In particular, in the fishing line of the present invention, it is preferable to use a polyamide-based resin or an aliphatic polyester because of excellent stretchability (instant recovery) and excellent workability.
また、芯糸となる熱可塑性樹脂モノフィラメントの直径は、特に限定はされないが、十分な伸縮性と高強度を両立させるために、０．０１〜０．４ｍｍの範囲が好ましく、さらには０．０２〜０．３ｍｍの範囲がより好ましい。 The diameter of the thermoplastic resin monofilament used as the core yarn is not particularly limited, but is preferably in the range of 0.01 to 0.4 mm, and more preferably 0.02 in order to achieve both sufficient stretchability and high strength. A range of ˜0.3 mm is more preferable.
一方、本発明の釣り糸を構成する鞘糸は、その素材や特性については特に限定はされないが、破断強度が１３ｃＮ／ｄｔｅｘ以上であり、且つ弾性率が３５０ｃＮ／ｄｔｅｘ以上であることが好ましく、さらに生産性の観点から、破断強度１８ｃＮ／ｄｔｅｘ以上、弾性率４００ｃＮ／ｄｔｅｘ以上であることがより好ましい。また、鞘糸の破断強度および弾性率の上限には特に制限はないが、破断強度の上限は３５ｃＮ／ｄｔｅｘ程度、弾性率の上限は５００ｃＮ／ｄｔｅｘ程度であることが望ましい。 On the other hand, the sheath yarn constituting the fishing line of the present invention is not particularly limited in terms of its material and characteristics, but preferably has a breaking strength of 13 cN / dtex or more and an elastic modulus of 350 cN / dtex or more. From the viewpoint of productivity, it is more preferable that the breaking strength is 18 cN / dtex or more and the elastic modulus is 400 cN / dtex or more. The upper limit of the breaking strength and elastic modulus of the sheath yarn is not particularly limited, but the upper limit of the breaking strength is preferably about 35 cN / dtex, and the upper limit of the elastic modulus is preferably about 500 cN / dtex.
この理由は、鞘糸が破断強度および弾性率が上記範囲を下まわる場合は、低強度や伸縮性に欠けた釣り糸となりやすいからである。 This is because when the scabbard thread has a breaking strength and an elastic modulus that fall below the above ranges, it tends to be a fishing line lacking in low strength and stretchability.
したがって、鞘糸が上記条件を満たせば、鞘糸の素材については特に限定はされないが、本発明の釣り糸においては、鞘糸が高密度ポリオレフィン繊維、アラミド繊維、ポリアリレート繊維、金属細線であることがより好ましい。 Therefore, if the sheath yarn satisfies the above conditions, the material of the sheath yarn is not particularly limited, but in the fishing line of the present invention, the sheath yarn is a high-density polyolefin fiber, an aramid fiber, a polyarylate fiber, or a fine metal wire. Is more preferable.
なお、鞘糸の単糸繊度は、特に限定はされないが、釣り糸を出来るだけ細く仕上げることができるとの理由から、単糸繊度が０．５〜１５ｄｔｅｘの範囲が好ましく、さらには１．０〜１０ｄｔｅｘの範囲がより好ましい。 The single yarn fineness of the sheath yarn is not particularly limited, but the single yarn fineness is preferably in the range of 0.5 to 15 dtex, and more preferably 1.0 to 1.0 because the fishing line can be finished as thin as possible. A range of 10 dtex is more preferred.
本発明の釣り糸は、その直径が０．０５ｍｍ〜０．６ｍｍの範囲にあることが必要であり、さらには０．１ｍｍ〜０．５ｍｍの範囲にあることがより好ましい。 The fishing line of the present invention needs to have a diameter in the range of 0.05 mm to 0.6 mm, and more preferably in the range of 0.1 mm to 0.5 mm.
もし、直径が上記範囲を下回る場合は、魚が釣り針に掛かった際の引きに耐えることができず、釣り糸が切れやすくなり、逆に、直径が上記範囲を上回る場合は、釣り糸の剛性が高くなるため、釣り糸として扱いにくくなるばかりか、流水抵抗や空気抵抗を受けやすくなるために棚を合わせにくくなり、釣果に影響を及ぼす傾向にあるため好ましくない。 If the diameter is below the above range, the fish will not be able to withstand pulling when hooked on the fishhook, and the fishing line will break easily. Conversely, if the diameter exceeds the above range, the fishing line will have high rigidity. Therefore, not only is it difficult to handle as a fishing line, but it is not preferable because it tends to be affected by running water resistance and air resistance, making it difficult to align shelves and tending to affect fishing results.
さらに、本発明の釣り糸は、その破断強度が１５００Ｎ／ｍｍ２以上、破断伸度が１０〜４０％の範囲にあることが必要であり、特に破断強度１７００Ｎ／ｍｍ２以上、２７００Ｎ／ｍｍ２以下、破断伸度１５〜３５％の範囲にあることがより好ましい。 Furthermore, the fishing line of the present invention needs to have a breaking strength of 1500 N / mm 2 or more and a breaking elongation of 10 to 40%, particularly breaking strength of 1700 N / mm 2 or more and 2700 N / mm 2 or less. More preferably, the elongation at break is in the range of 15 to 35%.
この理由は、釣り糸の破断強度が上記範囲を下回る場合は、釣り糸としての十分な強度が発揮されないからである。また、破断伸度が上記範囲を下まわる場合は、魚が掛かった際に魚が逃げようとして暴れると、釣り糸がその振動を十分に吸収できず、魚が針から外れて逃げてしまいやすくなり、逆に、破断伸度が上記範囲を上回る場合は、魚が掛かった時の当たりが伝わりにくく、合わせのタイミングを逃してしまい、釣果に影響を及ぼす場合があるからである。 This is because when the breaking strength of the fishing line is below the above range, sufficient strength as a fishing line is not exhibited. Also, if the elongation at break is below the above range, if the fish catches up and goes wild when the fish tries to escape, the fishing line will not be able to absorb the vibration sufficiently, and the fish will easily escape from the needle and escape. On the contrary, when the breaking elongation exceeds the above range, the hit when the fish is caught is not easily transmitted, and the timing of the alignment is missed, which may affect the fishing result.
さらにまた、本発明の釣り糸は、長さＨ０の釣り糸に引張速度３００ｍｍ／分で荷重を掛けてゆき、破断強度の５％の荷重が掛かった時点の釣り糸の長さをＨ、さらに破断強度の５％の荷重を１分間掛けた状態で放置した後、３００ｍｍ／分の速度で荷重を取り除いた後の釣り糸の長さをＨ１とした際に次式１００×（Ｈ−Ｈ１）／（Ｈ−Ｈ０）で求められる瞬間回復率が７０〜１００％の範囲にあることが必要であり、さらには７５〜１００％の範囲にあることが好ましい。 Furthermore, the fishing line of the present invention, Yuki by applying a load at a rate of 300 mm / min tensile fishing line length H 0, the length of the fishing line at the time when 5% of the load of the breaking strength is applied H, further breaking strength When the length of the fishing line after removing the load at a speed of 300 mm / min is H 1 , the following formula 100 × (H−H 1 ) / (H-H 0) at sought instantaneous recovery rate is required to be in the range of 70% to 100%, more preferably in the range of 75% to 100%.
もし、瞬間回復率が上記範囲を下まわる場合は、伸縮性に欠けた釣り糸が得られやすく、この釣り糸をスピニングリールに巻き、実際にルアーフィッシングなどの釣りを行うと、バックラッシュが発生しやすくなるからである。 If the instantaneous recovery rate falls below the above range, it is easy to obtain a fishing line lacking elasticity, and if this fishing line is wound on a spinning reel and fishing such as lure fishing is actually performed, backlash is likely to occur. Because it becomes.
なお、本発明の釣り糸には、芯糸を構成する熱可塑性樹脂モノフィラメントおよび／または鞘糸を構成する繊維に、本発明の目的を阻害しない範囲で、酸化チタン、酸化ケイ素、炭酸カルシウム、炭酸マグネシウム、炭酸バリウム、硫酸バリウム、硫酸カルシウム、燐酸バリウム、燐酸リチウム、燐酸カルシウム、燐酸マグネシウム、酸化アルミニウム、酸化ジルコニア、フッ化リチウム、カオリン、タルク等の無機粒子、耐熱剤、耐候剤、耐光剤、耐加水分解剤、紫外線防止剤、酸化防止剤、帯電防止剤、平滑剤、ワックス類、シリコーンオイル、界面活性剤、染料、顔料などの公知の添加剤成分を必要に応じて任意に添加することもできる。 In addition, the fishing line of the present invention includes titanium oxide, silicon oxide, calcium carbonate, magnesium carbonate within the range that does not impair the object of the present invention to the thermoplastic resin monofilament constituting the core yarn and / or the fiber constituting the sheath yarn. , Barium carbonate, Barium sulfate, Calcium sulfate, Barium phosphate, Lithium phosphate, Calcium phosphate, Magnesium phosphate, Aluminum oxide, Zirconia, Lithium fluoride, Kaolin, Talc, etc. A known additive component such as a hydrolyzing agent, an ultraviolet ray inhibitor, an antioxidant, an antistatic agent, a smoothing agent, waxes, silicone oil, a surfactant, a dye, or a pigment may be optionally added as necessary. it can.
上記各条件を満たした本発明の釣り糸は、釣り糸としての十分な強度を持ち、従来の新素材釣り糸に比べて適度な伸びと伸縮回復性をバランス良く兼ね備え、且つ従来のモノフィラメント製釣り糸と同等の扱い易さを有するため、船釣り用途や投げ釣り用途をはじめ、ルアーフィッシングや磯釣りなど、従来の新素材釣り糸では使用が難しかった釣り用途にも使用することができるが、さらに次の条件を満たすことにより、実際の釣りにおいてより際立った効果を取得することができる。 The fishing line of the present invention satisfying each of the above conditions has sufficient strength as a fishing line, has a proper balance of elongation and expansion / contraction recovery in comparison with a conventional new material fishing line, and is equivalent to a conventional monofilament fishing line. Because it is easy to handle, it can be used for fishing applications that were difficult to use with conventional new fishing lines, such as boat fishing applications, throw fishing applications, lure fishing, carp fishing, etc. By satisfying, it is possible to obtain a more remarkable effect in actual fishing.
すなわち、本発明の釣り糸においては、釣り糸を構成する芯糸の１０％伸張時の強度が１００〜５００Ｎ／ｍｍ２の範囲にあることが好ましく、さらには２００〜４００Ｎ／ｍｍ２の範囲にあることがより好ましい。 That is, in the fishing line of the present invention, the core thread constituting the fishing line preferably has a strength at 10% elongation in the range of 100 to 500 N / mm 2 , and more preferably in the range of 200 to 400 N / mm 2. Is more preferable.
これは、芯糸の１０％伸張時の強度が上記範囲を満たす場合は、釣り糸に加工したときの伸びと瞬間回復率のバランスに優れた釣り糸が得られるからである。 This is because, when the strength at the time of 10% elongation of the core yarn satisfies the above range, a fishing line excellent in the balance between elongation when processed into a fishing line and instantaneous recovery rate can be obtained.
また、本発明の釣り糸においては、その表面に芯糸と同じ熱可塑性樹脂からなるコーティングが施されている場合には、竿ガイドとの接触による鞘糸の摩耗を低減することができるとともに、コーティングに芯糸と同じ熱可塑性樹脂を使用するため、芯糸と鞘糸との密着性が向上し、芯糸と鞘糸との層間剥離を抑制することができる。 In the fishing line of the present invention, when the surface is coated with the same thermoplastic resin as the core thread, the wear of the sheath thread due to contact with the rod guide can be reduced, and the coating Since the same thermoplastic resin as the core yarn is used, the adhesion between the core yarn and the sheath yarn is improved, and delamination between the core yarn and the sheath yarn can be suppressed.
さらに、本発明の釣り糸には、本発明の目的を阻害しない範囲で、その表面に撥水処理、親水処理、表面硬化処理、柔軟化処理など各種表面処理を適宜施すことも可能である。 Furthermore, the surface of the fishing line of the present invention can be appropriately subjected to various surface treatments such as water repellent treatment, hydrophilic treatment, surface hardening treatment, and softening treatment as long as the object of the present invention is not impaired.
本発明の釣り糸は、例えば次の方法により製造することができる。 The fishing line of the present invention can be manufactured, for example, by the following method.
まず、釣り糸を構成する芯糸は、何ら特殊な方法で製造する必要はなく、例えば公知の溶融紡糸法などにより製造することができる。 First, the core yarn constituting the fishing line need not be produced by any special method, and can be produced, for example, by a known melt spinning method.
そして得られた芯糸に、この芯糸を構成する熱可塑性樹脂モノフィラメントの破断強度の１０〜２０％に相当する張力を掛けた状態で、芯糸の周囲に鞘糸をＳ方向およびＺ方向に交互に巻き付けながら製紐したり、撚り合わせたりすることにより、芯糸と鞘糸を組み合わせていく。 And in the state which applied the tension | tensile_strength corresponded to 10 to 20% of the breaking strength of the thermoplastic resin monofilament which comprises this core thread to the obtained core thread, a sheath thread was put in the S direction and the Z direction around the core thread. The core yarn and the sheath yarn are combined by stringing or twisting them while winding them alternately.
この場合に、芯糸に上記の範囲の張力を掛けないと、得られた釣り糸の伸びや伸縮性が小さくなることから、魚が掛かった際に魚が逃げようとして暴れると、釣り糸がその振動を十分に吸収できず、魚が針から外れて逃げてしまいやすくなるばかりか、スピニングリールに巻き、実際にルアーフィッシングなどの釣りを行うと、バックラッシュが発生しやすくなるため好ましくない。 In this case, unless the tension in the above range is applied to the core yarn, the elongation and stretchability of the obtained fishing line will be reduced. Is not sufficiently absorbed, and the fish tends to escape from the needle and escape, and if it is wound on a spinning reel and actually fishing such as lure fishing, backlash tends to occur, such being undesirable.
芯糸および鞘糸の割合については、特に限定はされないが、高強度や適度な伸縮性が得られることから、芯糸の割合が釣り糸全体の２０〜５０％、特に３０〜４０％の範囲にあることが好ましい。 The ratio of the core yarn and the sheath yarn is not particularly limited, but since the high strength and appropriate stretchability can be obtained, the ratio of the core yarn is in the range of 20 to 50%, particularly 30 to 40% of the entire fishing line. Preferably there is.
そして、さらに必要に応じて、釣り糸の表面に芯糸と同じ熱可塑性樹脂からなるコーディングを施すことにより、本発明の釣り糸が得られるのである。 Further, if necessary, the fishing line of the present invention can be obtained by applying a coating made of the same thermoplastic resin as the core thread on the surface of the fishing line.
以下に、本発明の釣り糸を実施例に基づいてさらに詳しく説明する。なお、実施例における釣り糸の評価は以下の方法で行った。 Below, the fishing line of this invention is demonstrated in more detail based on an Example. In addition, evaluation of the fishing line in an Example was performed with the following method.

[Breaking strength]
In accordance with JIS L1013, the tensile strength at break (N) was measured using a “Tensilon UTM-4-100 type” tensile tester manufactured by Orientec Co., Ltd., and the breaking strength per unit cross-sectional area of the fiber. (N / mm 2 ).
［破断伸度］
ＪＩＳ Ｌ１０１３に準じて、（株）オリエンテック社製「テンシロンＵＴＭ−４−１００型」引張試験機を使用して引張破断時の伸び率（％）を測定した。
[Elongation at break]
According to JIS L1013, the elongation rate (%) at the time of tensile fracture was measured using a “Tensilon UTM-4-100 type” tensile tester manufactured by Orientec Co., Ltd.
［瞬間回復率］
釣り糸を２０℃、６５％ＲＨの温湿度調整室で２４時間放置後、（株）オリエンテック社製「テンシロンＵＴＭ−４−１００型」引張試験機を使用し、長さＨ０＝２５ｃｍの釣り糸に引張速度３００ｍｍ／分で荷重を掛けてゆき、破断強度の５％の荷重が掛かった時点の釣り糸の長さをＨ、さらに破断強度の５％の荷重を１分間掛けた状態で放置した後、３００ｍｍ／分の速度で荷重を取り除いた後の釣り糸の長さをＨ１とし、次式１００×（Ｈ−Ｈ１）／（Ｈ−Ｈ０）から瞬間回復率（％）を求めた。瞬間回復率の値が大きいほど伸縮性に優れた釣り糸であることを示す。
[Instant recovery rate]
After leaving the fishing line in a temperature / humidity adjustment room at 20 ° C. and 65% RH for 24 hours, use a “Tensilon UTM-4-100 type” tensile tester manufactured by Orientec Co., Ltd. and use a fishing line with a length H 0 = 25 cm. After applying a load at a tensile speed of 300 mm / min, the length of the fishing line at the time when a load of 5% of the breaking strength was applied was H, and after being left under a condition of applying a load of 5% of the breaking strength for 1 minute. , the length of the fishing line after removal of the load at 300 mm / min and H 1, was determined instantaneous recovery rate (%) from the following equation 100 × (H-H 1) / (H-H 0). It shows that it is a fishing line excellent in elasticity, so that the value of an instantaneous recovery rate is large.

[Comparative Example 5]

［比較例６］
芯糸を直径０．１００ｍｍのポリアリレートマルチフィラメント繊維（クラレ社製、ベクトラン）に変更した以外は、実施例１と同じ条件で釣り糸を作製した。得られた釣り糸の評価結果を表１に示す。
[Comparative Example 6]
A fishing line was produced under the same conditions as in Example 1, except that the core yarn was changed to polyarylate multifilament fiber (Kuraray, Vectran) having a diameter of 0.100 mm. Table 1 shows the evaluation results of the obtained fishing line.
表１の結果から明らかなように、本発明の釣り糸（実施例１〜６）は、いずれも破断強度が１５００Ｎ／ｍｍ２以上、且つ破断伸度が１０〜４０％の範囲にあるため、釣り糸としての十分な強度と魚が掛かった際の吸収性を兼ね備え、さらに瞬間回復率が７０〜１００％の範囲にあるため、スピニングリールを使い軽いルアーを投げた場合でも、バックラッシュが発生しないなど、従来の新素材釣り糸では得られなかった様々な効果を発揮し、極めて実用性の高い釣り糸であることが分かる。 As is clear from the results in Table 1, the fishing line (Examples 1 to 6) of the present invention has a breaking strength of 1500 N / mm 2 or more and a breaking elongation of 10 to 40%. Combined with sufficient strength and absorbability when fish is applied, and since the instantaneous recovery rate is in the range of 70-100%, even if a light lure is thrown using a spinning reel, backlash does not occur, etc. It can be seen that the fishing line exhibits various effects that cannot be obtained with the conventional new material fishing line and is a highly practical fishing line.
一方、熱可塑性樹脂モノフィラメントを芯糸として使用していない釣り糸（比較例１）は、釣り糸の破断伸度が低く、瞬間回復性が全くないため、実際に釣りに使用した場合、掛かった魚が針から外れて釣り逃がしてしまいやすいばかりか、スピニングリールを使い軽いルアーを投げた際にはバックラッシュが頻繁に発生し、極めて扱いにくいものであった。 On the other hand, the fishing line that does not use the thermoplastic resin monofilament as the core thread (Comparative Example 1) has a low breaking elongation of the fishing line and has no instantaneous recovery. Not only was it easy to miss fishing off the needle, but when a light lure was thrown using a spinning reel, backlash frequently occurred and it was extremely difficult to handle.
また、芯糸のみからなる釣り糸、つまり従来の熱可塑性樹脂モノフィラメントからなる釣り糸（比較例２）は、芯糸および鞘糸からなる釣り糸に比べて破断強度が低いため、実際に釣りに使用した場合、魚か掛かった時に、釣り糸が切れて魚を釣り逃がしてしまいやすいなどの点で実用性に欠けたものであった。 Moreover, the fishing line consisting only of the core yarn, that is, the fishing line consisting of the conventional thermoplastic resin monofilament (Comparative Example 2) has a lower breaking strength than the fishing line consisting of the core yarn and the sheath yarn. When the fish was hung, it was lacking in practicality in that the fishing line was cut and it was easy to miss the fish.
さらに、破断強度および破断伸度が本発明の条件を満たさない鞘糸を使用した釣り糸（比較例３、４）は、釣り糸の破断強度が低いため、実際に釣りに使用した場合、魚か掛かった時に、釣り糸が切れて魚を釣り逃がしてしまいやすいなどの点で実用性に欠けたものであった。 Further, the fishing line using the sheath yarn whose breaking strength and breaking elongation do not satisfy the conditions of the present invention (Comparative Examples 3 and 4) has a low breaking strength of the fishing line. When the fishing line was cut, the fishline was cut and the fish were easily missed.
さらにまた、芯糸にマルチフィラメントを使用した釣り糸（比較例５および６）は、破断強度が低く、破断伸度および瞬間回復率も低いため、実際に釣りに使用した場合、掛かった魚が針から外れて釣り逃がしてしまいやすいばかりか、釣り糸が切れて魚を釣り逃がしてしまう場合も発生し、さらにはバックラッシュが頻繁に発生するなどの点で極めて扱いにくいものであった。 Furthermore, the fishing line using the multifilament as the core yarn (Comparative Examples 5 and 6) has a low breaking strength and a low breaking elongation and a low instantaneous recovery rate. In addition to being easy to escape from the fishing line, the fishing line may break and the fish may be missed, and the backlash frequently occurs.
以上説明したように、本発明の釣り糸は、釣り糸としての十分な強度を持ち、従来の新素材釣り糸に比べて適度な伸びと伸縮回復性をバランス良く兼ね備え、且つ従来のモノフィラメント製釣り糸と同等の扱い易さを有するため、船釣り用途、投げ釣り用途をはじめ、ルアーフィッシングや磯釣りなど、従来の新素材釣り糸では使用が難しかった釣り用途にも使用することができ、その実用性が極めて高い。 As described above, the fishing line of the present invention has sufficient strength as a fishing line, has a proper elongation and stretch recovery in a well-balanced manner compared to a conventional new material fishing line, and is equivalent to a conventional monofilament fishing line. Because it is easy to handle, it can be used for fishing applications that are difficult to use with conventional new material fishing line such as lure fishing and carp fishing, as well as boat fishing and throwing fishing, and its practicality is extremely high .
